As covered here last week, Norfolk has published a Missing Middle Pattern Book designed to make new housing development more streamlined and affordable. "People often visualize adding more units means that the building will get bigger and bigger, but some of the examples identified in the pattern book demonstrate that you can have a house-scale building with multiple units in it," says Dan Parolek, author of Missing Middle Housing.

Meanwhile, Arlington, where 75 percent of residential land is zoned for single-family homes, is considering relaxing its zoning code to allow a broader diversity of multi-family buildings. According to Arlington's comprehensive planning section supervisor, Kellie Brown, "[t]he existing zoning doesn’t allow for more missing middle housing, so there are limited opportunities to increase our housing supply under many local ordinances today." Creating the opportunity for more housing means reforming other restrictive regulations such as parking requirements and minimum lot sizes.
